Hallo
I would like to update my mediawiki because I want to to configere Echo Extention and I'm trying to do this through the web using mw-config.
but when I put the key assigned to $wgUpgradeKey that I found in my LocalSettings.php I receive this message The upgrade key you provided is incorrect.
There is a special way to write this key I just made cut and paste from the file LocalSettings.php.
thanks
